Update:
I just tried it again with antialising, and the render time didn't 
really go up that much. Evidently, the last time I tried aa the texture 
had a lot of noise in it. Also, removing the surface normal considerably 
decreases render time.

I attached two more images. The first one has the surface normal in 
place and uses aa. The second uses no surface normal, but still has aa. 
The render times are diplayed in the lower right corner of each image.
